SUITCASE SNAP-BOLT.

Specification of Letters Patent.

Application filed August 18, 1915. Serial N o. 46,075.`

To all whom t may concern Be it known that I, CHARLES ROSENBLUM, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Suitcase Snap-Bolt, of which the following is a full,clear, and exact description.

This invention relates to temporary hasps or fasteners for receptaclesand is adapted especially for travelers suitcases or the like.

Among the objects of the invention is to construct a fastener or haspcomprising a stud for attachment to onev part of the receptacle and atongue part carried by another part of the receptacle movable relativelyto the first part mentioned and cooperating with said stud, a peculiarform of spring being provided to make the coperation between the studand tongue more secure.

lVith the foregoing and other objects in view, the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed herein, still for the purpose of illustratinga practical embodiment thereof reference is had to the accompanyingdrawings, in which like reference characters designate the same parts inthe several views, and in which- Figure 1 is a perspective view of aportion of a receptacle having one form of my invention applied thereto;Fig. 2 is a vertical sectional view of the same on the line 2 2 of Fig.1; and Fig. 3 is a detail view indicating the form of the spring and thecup for securing it in position.

Referring now more particularly tov the drawings, l show a receptaclewhich may be regarded as a suitcase 10 having a relatively movable toplid 11. The fastener comprises a stud 12 carried by a plate 13 securedrigidly and permanently as by rivets 14 or their equivalent to the mainpart of the receptacle. The other main portion of the fastener comprisesa tongue or plate 15 carried by a plate 16 secured firmly as by rivetsor the like to the cover 11. The tongue may be hinged as indicated at18, if desired, to facilitate the action thereof with respect to thestud. The base 13 and the tongue may be provided with circumferentialribs, as indicated at 19 and 2O respectively, to stiffen and strengthenthe same. That portion 21 of the tongue within the rib 2O is fiat andlies closely against the outer face of the base 13 and is provided witha central hole concentric with both of the ribs through which the studprojects.

The numeral 23 indicates a cup having a series of spurs 24 projectinginwardly from the rim thereof through correspondingly formed holes inthe plate 21. The outer face of the cup is fiat and provided with acentral hole 25 through which the stud projects, the hole beingsubstantially of the same diameter as the head of the stud. This cup 23constitutes a holder for a spring 26 in the form of an equilateraltriangle, each side of which spans a portion of the hole 25 as noted inFig. 3; thereby the spring bears upon the stud l2 at three diiierentpoints. The spring may be made at very low cost and the assemblage ofthe parts may be effected with facility. The cup 23 with its flat faceand circular rim retains the spring in operative position but permitsfree rotation Y or {ioating thereof around the aXis of the hole 25. Thisfree rotation or floating ac- Patented June 6, 1916.`

tion of the spring around the aXis of the stud provides not only aneasier action of the fastener in locking or unlocking, but also servesto distribute the wear between it and the stud to all parts of the studssurface. The tongue member may be provided with a downwardly andoutwardly projecting lip 27 to facilitate the disconnection of the twomain parts.

The main strain resisting the opening movement of the lid 11 is bornedirectly between the tongue or plate member 15 and the rigid stud, thespring serving only to prevent the outward movement of the tongue ordisplacement from the stud. While the force of the spring is sufficientto prevent this accidental separation of the parts, it is not so greatas to render the device difficult to open in its intended way, byapplication of the force of a finger to the lip 27.

I claim z- 1. The combination with the main part of a receptacle and arelatively movable part thereof, of a fastener comprising a base platesecured to one of the receptacle parts, a rigid stud carried by the baseplate, a tongue member carried by the other receptacle part and having ahole adapted to receive said stud, a cup secured to the tongue andcomprising a flat outer face and a circular rim, said cup face having ahole in alinenient with the tongue hole, and a straightsided Springcarried Within the tongue cup and intersecting a plurality of portionsof the hole providing a similar number ot' holding` Contact pointspreventing separation of the tongue from the stud, Said spring` beingrotatable Within the cup freelj)T around the axis of the stud.

2. A fastener of the character set forth Comprising a base, a rigid Studcarried by the base, a plate member having a rhole adapted to receivesaid stud, a eup secured to the plate member and Comprising a lat outerface and a circular rim, Said oup face having a hole in alnement Withthe plate hole, means to secure the cup rim to the plate, and anequilateral triangularly Shaped spring carried Within the cup andintersecting three portions of the alined holes providing a like numberof holding` Contact points preventing separation of the plate from. thestud, Said spring being rotatable Within the eup freely around the axisof the stud.
